(multi-tap keys)
D
pastes the natural logarithm, ln, of a number to the base e. The argument of the
function is
ln(
value
)
.
e ≈ 2.718281828459 for calculations.
e ≈ 2.718281828 for display in Float mode.
D D
pastes the common logarithm, log
10
, of a number. The argument of the
function is
log(
value
)
.
D D D
pastes the logBASE function as a MathPrint™ template. When
needed, the arguments in classic entry are
logBASE(
